Add external libraries to CMakeList.txt c++

Question

I have my external library as shown in this picture that I create the symbolic links after:

and the headers related to the library in other file:

I'm working with ROS ubuntu and I need to add these libraries to my package to CmakeList.txt:

cmake_minimum_required(VERSION 2.4.6) include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)  rosbuild_init()  #set the default path for built executables to the "bin" directory set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin) #set the default path for built libraries to the "lib" directory set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)  #common commands for building c++ executables and libraries #rosbuild_add_library(${PROJECT_NAME} src/example.cpp) #target_link_libraries(${PROJECT_NAME} another_library) #rosbuild_add_boost_directories() #rosbuild_link_boost(${PROJECT_NAME} thread) #rosbuild_add_executable(example examples/example.cpp) #target_link_libraries(example ${PROJECT_NAME})  rosbuild_add_executable(kinectueye src/kinect_ueye.cpp) 

So my question is how can I add these folders (I think the first one that I need to add I'm not sure) to my CmakeList.txt file so as I can use the classes and the methods in my program.

I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

INCLUDE_DIRECTORIES(your/header/dir) LINK_DIRECTORIES(your/library/dir) rosbuild_add_executable(kinectueye src/kinect_ueye.cpp) TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...) 

note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them
